Structural Steel Connections The Green Book Pdf File

The Green Book is famous for its design tables. For a given beam size, steel grade (e.g., S275), and bolt diameter (e.g., M20), the tables directly give:

Example from Table 5.2 (Fin Plate – S275 steel, M20 bolts, 10 mm plate):

Note: These are illustrative values; refer to the actual P212 for exact tabulated data. structural steel connections the green book pdf

Each table gives maximum design shear resistance (kN) for different:

You check: Is your required shear load ≤ the tabulated value? The Green Book is famous for its design tables

The tables assume:

If your case differs (e.g., long connection, thick beam flange >40mm), you may need a direct calculation or the companion design manual (SCI P398). Example from Table 5

In structural steel design to Eurocode 3 (BS EN 1993-1-8), joints are classified as simple, rigid, or semi-rigid. Simple connections assume no significant moment transfer, only shear and axial forces. The Green Book (SCI P212) provides standardized, pre-qualified details for such joints, allowing designers to avoid complex finite element analysis. The core philosophy is that the connection must be sufficiently ductile to accommodate the rotation required under load without exceeding its resistance.

The story of the Green Book is best understood by watching a design team in action:
